Questions regarding heat exchangers for refrigerant R410A! ! !
Thread Content
Dear experts in this forum, when using R410A as a refrigerant, here are the considerations for designing shell-and-tube heat exchangers (dry evaporators and condensers): 1. For example, how should the areas of shell-and-tube evaporators and condensers be compared compared to those using R22? 2. Is it necessary to increase the thickness of the heat exchange tubes? 3. Are there any other details that need attention?
Why isn’t there any sound! Gurus!
I’m not very familiar with the manufacturing process. For heat exchangers using R404A and compressed natural gas, we mainly need to pay attention to the effects of welding stress in order to prevent welding deformation. Another critical aspect is the sealing surface where the tube sheet meets the flange; the selection of gaskets is also important here.
